Drought is a serious natural hazard that affects all climatic regions in so much that more than half of the world is under the threat of drought each year. Lack of precipitation is the principal reason for all types of drought. The causes for this phenomenon to occur may be sub-normal rainfall, uneven rainfall distribution, greater requirement of water than availability or the combinations of all the three. Meteorological drought is usually defined on the basis of the degree of dryness (in comparison to some “normal” or average amount) and the duration of the dry period. Some widely used and advanced meteorological drought indices are Rainfall Anomaly Index, Palmer Drought Severity Index, Bhalme and Mooley Drought Index, Drought Severity Index, Standardized Precipitation Index (SPI), Effective Drought Index and Reconnaissance Drought Index. Standard Precipitation Index (SPI) overcomes the traditional drought indices. In the present study, meteorological drought assessment has been carried out at Satna and Tikamgarh districts of Madhya Pradesh using Standard Precipitation Index (SPI). The SPI values have been calculated on 3 month and 12 month time scales for the duration of 1981-2017 and then drought classification of the study area has been done using the SPI values. Mann Kendall Non Parametric Test has also been applied on the calculated SPI values to detect the presence of trend in the SPI values. The results from SPI values show that Tikamgarh district has extreme drought condition and there is severe drought condition in Satna districts. The trend analysis of the SPI values show that there is no trend present in the SPI values in any of the studied districts. The results of the present drought assessment study will thus help the water managers & policymakers to take further adaptation steps to eradicate and mitigate the chances and effects of future expected droughts.
